'IO ALL WHOM I'I MAY CONCERN:

Be it known that we, ANDREW FULLER and FRANCIS J. BRAY, of Buffalo, in the county of Erie, in thc State of New York, have invented certain new and useful Improvements in Suckers for CanalBoat Pumps; and we do hereby declare that the following is a full and exact description thereof, reference being had tothe accompanying drawings, and to the letters of reference marked thereon.

The nature oi' our invention consists in providing the stati andvsucker with elastic'strips, said strips holding the upper rim of said sucker to the stati'.

To enable othersskilledin the art to make and use our invention, we will proceed to describe its construction and operation. I I

In the drawings, the saine letters in Figures 1 and 2 represent similar parts in each.

Figure 1 represents a side elevation ot' the pump stati' and sucker, also the elastic strips for holding the upper part ofV the sucker to said stai?.

Figure 2 is also a side elevation showingzthe pump complete with the stati and sucker in place, the dotted lines representingtheir position within the pump.

In iig. 1, A and G represent the stati' and handle to the pump; H the suckcryC B and D the elastic strips for drawing it upward and holding it firmly to the staff. They are firmly fastened at their upper extremities by either tacks or screws, as shown at E; the lower part of the sucker isfastened inl a similar manner, as shown at F. These elastic strips, by extending downward during the action of lifting the water, allows the upper rim of the Asucker to spread, which eiectually closes thev space between-.the sides of the pump and the same. I

represents that part of the suekel` which is most exposed to wear by rubbingalong the sides of thc pump during the action of pumping. It is made thicker than the rest of' the sucker for the purpose of giving it greater durability. I

The old sucker of leather in a short time becomes useless, as the water softens it, and the upper edge or rim is apt to turn over during the action of pumping. Our invention, we claim, overcomes this difiiculty, as the rubbe-r does not soften by standing in water, and it works better and is much more durable.

What we claim as our invention, and desi-'reto secure by Letters Patent, is-

The elastic strips C, B, and D, in combination with th"e stalA and sucker H, substantially as described.
